Android数据库的增删改查和ListView以及页面跳转的实现

不多说甚么，直接看代码：先创立一个person实体对象。

import java.io.Serializable;

public class Person implements Serializable{
	private static final long serialVersionUID=1L;
	private Integer id;
	private String name;
	private String phone;
	private Integer amount;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	public Integer getAmount() {
		return amount;
	}
	public void setAmount(Integer amount) {
		this.amount = amount;
	}
	public Person(String name, String phone, Integer amount) {
		super();
		this.name = name;
		this.phone = phone;
		this.amount = amount;
	} 
	public Person(int id,String name, String phone, Integer amount) {
		super();
		this.id=id;
		this.name = name;
		this.phone = phone;
		this.amount = amount;
	}
